A Novel Technique for Improving Temperature Independence of Ring-ADCs
-
Abstract
A new temperature compensation technique for ring-oscillator-based ADCs is proposed.This technique employs a novel, fixed-number-based algorithm and CTAT current biasing technology to compensate the temperature-dependent variations of the output, thus eliminating the need for digital calibrations.Simulation results prove that, with the proposed technique, the resolution in the temperature range of 0 to 100℃ can reach a 2mV quantization bin size with an input voltage span of 120mV at the sampling frequency of fs=100kHz.-
